With the advanced Mempro™ nanodiscs analysis platform established for a long time, Creative Biostructure can offer tailored Mempro™ native PAGE services for nanodiscs analysis. Our experienced scientists are confident in providing high-quality native PAGE services to meet all your demands.
Native PAGE is a method developed to separate polypeptides via charge to mass ratio, which uses the identical inconsecutive chloride and glycine ion fronts as SDS-PAGE to generate moving boundaries that stack. To perform this technique, a non-reducing and non-denaturing sample buffer is necessary in which proteins remain in their secondary structure and native charge density. Hence, multiple bands enable to be seen from the camshot of the native PAGE gel if the target protein is in a protein complex in the sample. In native PAGE electrophoresis, the major positions of proteins present an acidic or basic pl (isoelectric point), which force them to move towards the polar. In addition, there are two basic forms of native PAGE, blue native PAGE (BN-PAGE) and clear native PAGE, which are both widely used in the nanodiscs analysis.
